Specialty: Ecology of coastal and marine resources
Hobby: fishing in mountain streams, cheering for Vegalta Sendai
Research theme:
We examine the ecology and production systems of aquatic biological resources from various points of view.
1. Connectivity of hills, humans and oceans (CoHHO)
We investigate integrated coastal zone management based on understanding of ecological relationships between terrestrial and coastal areas, including productivity and biodiversity that are strongly affected by human activities. We elucidate the ecological connectivities of forests, rivers and coastal ecosystems, and the impacts of human activities on coastal biological production systems. Management approaches for sustainable development will be identified and promoted based on the outcomes of the studies of connectivity.
2. Ecology and production of aquatic organisms
We also study production systems of aquatic biological resources. With an emphasis on food web structure, energy flow from nutrition and primary production to macrobenthos and fishes, life history, survival, growth, movement and feeding ecology of key species. We also study the ecological functions of habitats and habitat networks (complex ecosystem networks) for biological production in coastal areas such as river mouths, tidal flats, lagoons, sandy shores, rocky reefs, and seagrass and seaweed beds.
3. Management of aquatic biological resources
We examine management approaches from local to international level. We develop appropriate methods to manage resources, restore environments and enhance stocks.

Specialty: Fish psychology
Hobby: diving, tennis, marathon, piano
Research theme:
Fish psychology is a research field that deals with the behavior and ecology of fishes through an approach of experimental psychology. “How do fish maintain a school?”, “How smart can fish be?”, “What will happen to fish populations if jellyfish blooms expand?” Research is often based on questions that arise from diving or talking with fishermen. Rearing experiments are then related to the fluctuation mechanism of pelagic fish stocks. We also conduct experiments and observations applicable to the improvement of releasing strategies in marine stock enhancement.

Specialty: Fish systematics
Hobby: Bass guitar
Research theme:
Fishes constitute more than one-half of the total number of living vertebrate species, exhibiting enormous diversity in morphology and ecology. In Japan, about 3800 species are recognized as valid species. We try to understand and describe their diversity and estimate how they have speciated and evolved by morphological and genetic (mtDNA and AFLPs, and so on) analyses.
1. Systematics of rockfishes, snailfises, and lumpsuckers
2. Phylogeography focusing on fishes of the Sea of Japan

Specialty: Coastal and estuarine ecology
Hobby: jogging, swimming, hiking
Research theme:
Coastal and estuarine areas are characterized by many anthropogenic modifications as well as high natural productivity. Water pollution, shore protection, land reclamation, dredging, etc. are threatening the survival of coastal and estuarine organisms. I study the ecology of fish and crustaceans, specifically their distribution, feeding habits, growth, and survival during the early life stages when they are vulnerable to environmental changes. I aim at finding our way of living with coastal and estuarine organisms on the basis of the understanding of their life histories.
1. Ecology of larval and juvenile fish
Early life history (e.g. migration, feeding, growth, survival) is key to understand essential environmental conditions for successful reproduction in each fish species.
2. Ecology of zooplankton
The ecology of copepods and mysids (e.g. position maintenance, feeding, growth, survival) is key to understand zooplankton production underlying fish production.
3. Production relative to environmental fluctuations
The dynamics of coastal and estuarine production can be explained by environmental fluctuations on various temporal scales (e.g. climate change, seasonal change, fortnightly tidal cycle).

Specialty: Ecology on invertebrates
Hobby: jogging, beachcombing, making an independent solar system
Research theme: Biology of the sea cucumber Apostichpus japonicus; Ecology of benthic organisms with topography and/or geography
1. Temporal occurrence of bivalve larvae in an exposed sandy shore
Sandy shores (beaches) are generally defined as wave-exposed coasts possessing sandy littoral and supralittoral zones. The fauna in sandy shores is different from that in sheltered (enclosed) ones. I’ve studied the early life ecology of bivalves to clarify the mechanisms and influences of wave-exposed levels on the inhabitant. In order to study bivalve larvae, I constructed a species identification method of bivalve larvae using molecular biological techniques based on PCR.
2. Landscape ecology of bivalves in brackish water
The ecology of the brackish bivalve species Corbicula japonica was studied focused on topography and/or geography at the river flat and the brackish lagoon.
3. Ecology of the sea cucumber Apostichopus japonicus
The sea cucumber A. japonicus shifts its habitat at each life history stage. Larvae are in the water column, juveniles are assumed to be among seaweed or shell reefs and adults seem to be abundant in the soft sediments or rocky shores. I’m planning to approach its complicated life.
